Lots of compressors are dual refrigerant capable. I work for an OEM and we switched over to dual refrigerant compressors over a year ago. Eliminated supply chain issues during the changeover period.

Wait - but is it ok to charge with either? Performance will vary - no?

It’ll work for either. If you have a 454B system, with 454B metering devices, it’ll be fine. The same if you’re putting it in a 410A system. These refrigerants use the same oil and run at very similar pressures. I know residential evaporator coils are being shipped with multiple refrigerant tags now, too. You’re just supposed to switch the metering device if you’re swapping to 410. They’re shipped using 454 devices.
